Re: How to test amp hour
Joe, your LiPo packs should surrive a long time, with such low current draw. 10 amps is nothing, compared to what sort of loads battery packs likes these work under, on monster truck, buggy, or other racing applications. It's not uncommon for these packs to deal with 30 or 40 amp continuous loads, and surges past 100 amps. Your excavator should be a walk in the park for them.
As far as charging, it's always best to let a pack cool, before you charge it, but as long as the pack is not super hot, it should be fine. Also, LiPo packs do not develope memories, so you can charge them anytime, even if not fully discharged. Also, the more I've read, the more I'm told you can charge a LiPo pack as many times as you like, in one day, with no ill effects, so given all that, I can only assume the life of your packs was decreased just from normal wear and tear.
As for the recommended storage voltage, I have no idea why they say to do it with 50% of the battery's capacity.
